S'IOP MECHANISM FOR TALKING-MACHINES.

Specification of Letters Patent. Patented S t, 3 1918 A Application filed April 8, 1915. Serial ms. 20,050.

To allwhom it may concern:

Be it known that we, PLINY CATUccI and ANTHONY Vassrnm, citizens of the United States, and residents of the city of Newark,

5 county of Essex, and State of New Jersey, have invented ccrtalii new and useful Improvements in Stop Mechanism for Talking Machines, of which the following is a specification.

The invention relates to means for auto matically starting and stopping the motor andthe turntable.

Numerous methods have been proposed forproviding automatic stop mechanism for disk talking machines, all of which, so far as we are aware, depend upon the travel of the tone arm across the face of the disk record for releasing some kind of trip device, said trip device actuating a brake. The

power of operating such brake is usually a spring set under tension upon the with-' drawal of the brake from contact with the turn-table or tablet support. lThe motive power for actuating the trip device comes 26 directly from the grooves in the record itself. As the stylus of the sound box fol lows the groove, the sound box and the sup porting tone arm are caused to travel in a horizontal plane across the face of the rec 80 ord, and if the trip mechanism works a trifle hard, the result is to crowd the stylus needie out of the groove and cause the same to skip across from one groove to another,

thereby producing a, disagreeable vgrating 85 sound and frequent failure to release the trip.

()ne of the objects of our invention is to provide a release mechanism capable of automatically starting the rotation of the 0 motor and the turn-table, and to' provide a stop mechanism, operating automatically to arrest the movement of the motor and turntable.

y 7 Another object of our invention is to provide n'ieans opcratable in conjunction with the turn-table spindle for automatically starting; and stopping the: ,motor and turntable. it

, A further object of ouri iuvention is the 9 revision of means for autiimatically startmg and stopping the mgtorand the turntable, of the character d scribed, simple in construction, thoroughly reliable and efli cient in its purpose, and inexpensive and e00 nomical to manufacture.

With these and other objects in view to be more fully set forth hereinafter, the inventlon consists in the novel construction, combination of elements, and arrangemet of parts which will be exemplified in the con struction hereinafter described in the specificat1on and illustrated in the accompanymg drawings considered. together or separately.

The inventive idea involved is capable of recelving a variety of mechanical expres sions, one of which for the purpose of illustrating the invention, is shown in the ac companying drawings.

The invention will be first described in connection with the accompanying dran ings illustrating one embodiment of our invention, wherein similar reference charactors are used to designate corresponding parts throu hout the severalviews, and then more speci the appended claims.

In our invention, as em plication, we depend upon the motor spring for power to actuate the starting and stop ping mechanism as designed and built into the motor at the time of its original construction. The invention can also-be ap pliedto existing types of talking machines by the utilization of a hollow turn-table spindle, as aflixing to such hollow herein.

In the embodiment of the invention form-- ing part of this application, the driving mandrel is made tubular for portion of its length, and inside of said tubular portion we inscrt mechanism which, when in operative position will cause a brake arm to impinge upon the edge nor brake disk. The rotation of the spindle itself serves to set a brake upon some rotating part of the motor.

In the embodimentof the invention herein described and illustrated, we permit the travel of the stylus needle across of the record to determine-the point at which the motor is to be stopped, and for this purpose we provi dean adjustable index arm, the point of which may be located at the inner ring of the record groove before startodied in this aphereinafter described, and by spindle the invention of the gover-= the facecally defined and indicated in.

a considerable ing the motor; after the motor is started this index will rotate with the tablet sup port or turn-table, and when the stylus needle has traversed the face of the record, the

point of the index, coming in contact Withthe stylus needle, or with some depending part of the sound box, Will arrest the IOtdtion of the index arm while the continued rotation of the n'mmlrel will. operate tho mechanism to set the ln-nke.

In the accompanying drawings forming a art of this spooifieation--- lligure 1 is a, plan view of the exposed portion of our improved stop mechanism, the same comprising the adjustable (gout-aetarm; the )osition of the arm being shown as adjusted to the inner groove of the record tablet. Thev position of the sound box is also shown in dotted lines.

.1 rm agh eontri u go i added travel of the collar 17 so as to the direction of the artow 39. The adjustable arni Benn mm b% adjusted so that its up the cam 8 of the sleeve 7, and rest upon the horizontal plane against the shoulder 9; this operation, it will be noted, will cause the collar 17 to rise into the dotted line position shown in Fig. 3, thereby releasing the spring 31 from the edge of the disk 28. The governor is therefore free and the motor can begin to run. The-tone arm 41 and sound box 42 may then be adjusted to playing posi tion, and of course, the record groove will cause the sound box to traverse the face of the record 38 until such time as the stylus 43 begins to traverse the inner record groove. It Wlll be understood that the detachable arm 34, and the adjustable arm 36, are rotating with the mandrel 1 and record 38.

W'hen the stylus 43 reaches the inner record groove, the point 40" of the arm 36 will engage the stylus and therefore arrest the rotation of the arm 34, but since this arm 34 is connected to the spindle 3, the con tinued rotation of the mandrel 1 andsleeve 7, will cause the projection 12 to ride from the high portion of the cam 8 to thelower portion of the same, and thereb roduce a vertical downward movement 0 t. e spin- (he 3, carrying with it the collar 17 under the impulse of the spring 6, but the downward movement of the collar 17 will carry with it the brake spring 31, causing its outer end to bear with considerable pressure upon the edge of the brake disk 9/8, and thereby immediately arresting the rotation of the governor and consequently stopping the motor. The threading of the spindle 4 into the apertured arm 19, serves the additional purpose of giving the collar 17 a slightly greater motion along the-mandrel 7, than would be produced by the cam 8 alone; but since the cam 8 must bclimitcd, slightly less than the circumference of the sleeve 7, and all of-the parts must be contained in the interior of the mamlrcl 1, the easy working of the parts requires that the cum 8 should be a spiral of comparatively short pitch; otherwise the friction of the cam 12 against. the cam 8 would make the parts work hard. By threading the lower ends of the spindle 3 at 4, we are enabled to produce the requisitb roduce the requisite brake pressure upon tie edge of the brake disk 28,

In order to limit the rotation of the index 36 about the end of the arm 34, we provide side ofthe arm 34 when the index is in substantial alinement with the arm 34. In replacing a record upon the top of a mandrel 1, it is only necessary to remove the arm 34 from the squared portion 13, and place the record upon the mandrel; thereafter the arm may be returned to its place and the index 36 adjusted as above described.

It might be thought that the contact of the point of the index 36, with the stylus need e 43, would injure such stylus ne dle; this is a matter of minor importance for it is the custom to discharge such needle upon the completion of the playing of a record and its injury need not be considered.- In case, however, the stylus is a jewel, as diamond or sapphire the contact of the index with such stylus might be injurious. In that case, however, the sound box itself may be provided with a downward projection 95, upon its lower side, in position to enga e the point of the index 36, and thus avoi any contact whatsoever of the index with the stylus.

It will thus be seen that by the structure we are able to. accomplish the automatic stopping of the motor upon the completion of the record by mechanism which applies frictional resistance to the rotation of some part of the motor itself, and such frictional resistance is set in operation upon the comletion of the record by the motor itself.

n other words, the continued rotation of the motor appliesits own brake at a predetermined point in its 0 eration.

In accordance with t e provisions of the patent statute, we have described the principle of our invention together with the apparatus which we now consider to represent the best embodiment thereof, but we desire it understood that our invention is not con fined to the particular form of apparatus herein shown and described, the same being merely illustrative, and that the invention can be carried out in other ways without, departing from the spirit of our invention,

and, therefore, we claim broadly the right herein shown and described is only one of.

many that can be employed to attain these objects and accomplish these results.
